Hi and welcome to my basic review of my new NVME USB enclosure. Product details Simplecom SE513 NVMe PCIe (M Key) M.2 SSD to USB 3.1 Gen 2 Type C Enclosure 10Gbps Black Here's an image from the Simplecom website. I purchased this enclosure for ~50 bucks (posted) from Kogan, but they can be found at similar prices from many mainstream sources online. This image depicts the grey version, but they are also available in black, as mine is. Here's what came in the package. The enclosure 20cm USB C <> USB C cable. with a handy trapped Velcro strap for portability USB C <> USB A adapter a little screwdriver Here it is dismantled. Among the pile of stuff there you can see the 256GB Intel 760P NVME drive I'm fitting to this enclosure. Not the fastest of drives, but plenty good enough for a nice USB transport drive. Here's a link to the drive specs , which are nominally 3210MB/s read and 1315MB/ write when installed on a PCIE3 X4 NVME motherboard slot. Before installing the drive, I actually replaced the pictured end cap and removed the one from the other end, as I found it easier to install from the other end. The caps at either end are retained by 2 small screws. A drive retention screw was not included in the package, although there is a nut to screw it into. However, as it is quite a snug fit inside the enclosure, I felt it was not necessary, and not having a suitable screw handy, I simply slid it into the enclosure without the retention screw. This simply involved the removal of two tiny screws on the opposite end of the USB C port, removing the cap, sliding the board with the drive installed into the end, and replacing the cap. I connected it directly to the Gen 2 USB 3.1 header on my motherboard, simply because my computer case is in a state of flux right now and it was easier to access the header than the rear IO port. Firstly, I copied a 225GB folder, containing 495 individual TV episodes in .avi format, from a Seagate 2.5" 5200rpm spinning disk HDD onto the empty (formatted to NTFS [quick] ) NVME USB 3.1 drive. Speeds ranged from a maximum of about 107 MB/s to a minimum of 92 MB/s, remaining above 100 MB/s for the majority of the time. Clearly this is the limit of the source 2.5" Hard Drive rather than the USB drive. I then cut that folder from the USB drive and pasted it into a new folder on my 'C' drive, which is a 512GB Samsung 960 Pro. Sppeds ranged from a maximum of 378 MB/s to a minimum of 362 MB/s, mostly hovering around 370MB/s. SInce I'm copying via a Gen 2 3.1 header directly to a fast NVME onboard drive, the additional speed is immediately apparent. This is therefore about the maximum possible sustained read speed the enclosure and drive combination can offer. The 3rd test was cutting the same folder from my 'C' drive and pasting it back to the USB drive. Speeds ranged from an initial burst of 295MB/s to some short periods of 65MB/s, with one 5 second period dropping as low as 25MB/s. The first half of the transfer for the most part remained fairly steady at about 260MB/s, then during the second half began to pogo between about 270MB/s and 65MB/s, for periods of between 19-20 seconds on each bounce. Not as good as the read speeds, nor as consistent, but still not bad at all in my opinion. I was a little disappointed with the erratic speeds in the second half of the transfer, but still perfectly satisfactory given that this was a 225GB file transfer. While the drive was full, I then ran Crystal Disk on the drive. I wanted to see if the drive would be slower when full than it was when empty. I then formatted the drive to NTFS (quick) and repeated the Crystal Disk benchmark. It appears that the answer is no, there is little difference between full and empty when it comes to drive speed. CONCLUSION. I regularly kept feeling the enclosure as I did these tests. It got fairly warm, without actually getting too hot, so the aluminium body appeared to work quite well as a heat sink. Note that the drive started as a formatted (NTFS quick) drive, and all tests were performed back to back. The drive had no chance to cool from the first of these tests to the last. Given that it has done three 225GB transfers, back to back, I thought it did well for cooling. Speeds are not spectacular for an NVME drive, but as a 256GB USB 3.1 data transport drive (my main purpose being sustained sequential reads and writes) I would consider this drive to be quite quick for what it is. Construction is solid, and it should last for years to come. Of course, it could be used in a standard USB 3.0 port too, either via USB C or USB A using the provided adapter. Speeds would be considerably lower though, I was mainly interested in the high speed interface which is the one I am most likely to use, but I will certainly test it via slower interfaces sometime soon and post those results too. My single complaint is that I would have preferred it to have a male connection on the enclosure rather than a female, to allow use without a cable. A suitable cable to suit the male connector of course would still be useful, but I'm going to deduct one star due to requiring a cable at all to use it. I'm going to give it 4 Stars .
